WordCapData Expressions:

The Object property of the DataWindow control lets you specify expressions that referdirectly to the data of the DataWindow object in the control. This direct datamanipulation allows you to access small and large amounts of data in a single statement,without calling functions.

There are several variations of data expression syntax, divided into three groups. Thissection summarizes the syntax for the three groups. The syntaxes are described in detaillater in this chapter.Data in columns or computed fields when you know the nameOne or all items in the column (if rownum is absent, include either buffer or datasource)dwcontrol.Object.columnname {.buffer } {.datasource } { [ rownum ] }

Returns a single value (for a specific row number) or an array of values (when rownumis omitted).See One or all items in a named column or computed field .Selected items

dwcontrol.Object.columnname {.Primary }{.datasource }.Selected

Returns an array of values with an array element for each selected row.See Items in the column from selected rows .Range of itemsdwcontrol.Object.columnname {.buffer } {.datasource } [startrownum, endrownum ]

Returns an array of values with an array element for each row in the range.

See Items from a range of rows in a column or computed field .Data in numbered columnsSingle itemsdwcontrol.Object.Data {.buffer } {.datasource } [ rownum, colnum ]

Returns a single item whose data type is the data type of the column.See Single items .Blocks of data involving a range of rows and columnsdwcontrol.Object.Data {.buffer } {.datasource } [startrownum,startcolnum, endrownum,endcolnum ]

Returns an array of structures or user objects. The structure elements match the columns

in the range. There is one array element for each row in the range.See A block of rows and columns .Whole rowsSingle row or all rowsdwcontrol.Object.Data {.buffer } {.datasource } { [ rownum ] }

Returns one structure or user object (for a single row) or an array of them (for all rows).The structure elements match the columns in the DataWindow object.See Single rows or all rows .Selected rowsdwcontrol.Object.Data {.Primary } {.datasource } .Selected

Returns an array of structures or user objects. The structure elements match the columnsin the DataWindow object. There is one array element for each selected row.

See Selected rows .Summary of syntaxes

This diagram summarizes the variations in data expression syntax:

For information about getting and setting values of DataWindow object properties using

a similar syntax, see Basic syntax and Syntax for nested objects .Property Expressions:DataWindow property expressions use dot notation to specify the objects, objects withinobjects, and properties that you want to access.Syntaxdwcontrol.Object.dwobjectname {.Object.dwobjectnameproperty } {.propertyvalue }{ = value }Argument DescriptiondwcontrolThe name of the DataWindow control or child DataWindow in which youwant to get or set propertiesObjectObject indicates that subsequent elements refer to the object within dwcontrol or

dwobjectnamedwobjectnameAn object within the DataWindow. Possible values are DataWindow (for

properties that apply to the whole DataWindow) or the name of a bitmap, column,computed field, graph, line, oval, rectangle, round rectangle, report, TableBlob, or textobjectIf dwobjectname is a column with the DropDownDataWindow style, a reportobject, or an OLE object, you can specify another Object keyword and dwobjectname torefer to properties of objects within the nested object. You can specifyObject.dwobjectname as many times as needed to refer to a deeply nested reportFornested syntax, see "Syntax for nested objects"dwobjectnamepropertyA property that applies to dwobjectname. If the property requiresadditional qualifying properties, list the additional properties, separating them with adotFor lists of applicable properties, see the Property tables at the beginning of Chapter5, "DataWindow Object Properties"valueA string whose value is to be assigned to the propertyAlthough value is stored as astring, if the property value is a number value can either be a string whose value is anumber or a numeric data type. The value is stored as a stringIf the property value is ayes or no value, value can be either a string whose value is "yes" or "no" or a booleanvalue (TRUE or FALSE). The value is stored as "yes" or "no" stringsIf the propertyvalue can be an expression, then value can be a string that takes the form:defaultvalue~tDataWindowpainterexpressionwhere:?Defaultvalue is any value that is allowed for

property?DataWindowpainterexpression is an expression that can include names of

objects in the DataWindow and DataWindow painter functions?Defaultvalue andDataWindowpainterexpression are separated by a tab character (~t)For examples ofDataWindow painter expressions, see "Using DataWindow painter expressions"Return valueAny. The data type of the value is string.For more information about the expression's data type, see .ExamplesExample 1. In this statement, the boolean value FALSE is stored as the string "no":dw_1.Object.DataWindow.ReadOnly = FALSE

This statement displays the value of the ReadOnly property (either "yes" or "no") in the

StaticText st_status:st_status.Text = dw_1.Object.DataWindow.ReadOnly



11/21


When you test the value of a property in a relational expression, you must compare yourtest value to the stored values. For ReadOnly, stored values are yes or no, not booleanTRUE or FALSE:IF dw_1.Object.DataWindow.Readonly = 'yes' THENThis statement fails because the expression is not boolean:IF dw_1.Object.DataWindow.Readonly THEN // Not valid

Example 2. Valid values for the Visible property are 0 and 1. You can set the property tonumbers, yes and no, or TRUE and FALSE. Therefore, these three statements areequivalent:dw_1.Object.street.Visible = FALSEdw_1.Object.street.Visible = "NO"dw_1.Object.street.Visible = 0

Example 3. This example tests whether the X property contains a constant (which canbe converted to a number) or a DataWindow painter expression. A default value of 50 isspecified if the property contains an expression the script can't convert:

integer li_xIF IsNumber( dw_1.Object.id.X ) THEN

li_x = Integer( dw_1.Object.id.X )ELSE

li_x = 50END IF

Example 4. This script sets the X property to a DataWindow painter expression. Theexpression indents ID values for IDs less than 10:string modstring, ls_xls_x = "50"modstring = ls_x + "~t" + "If(id > 10, " + ls_x + "," + String(li_x + 20 ) + ")"dw_1.Object.id.X = modstring

Example 5. This example makes three columns updatable and reports the value of theUpdate property in the StaticText st_status. The reported value is "yes," not TRUE:dw_1.Object.id.Update = TRUEdw_1.Object.street.Update = TRUEdw_1.Object.last_name.Update = TRUEst_status.Text = "Updateable: id " + dw_1.Object.id.Update + ", street " + &

dw_1.Object.street.Update + ", last_name " + dw_1.Object.last_name.Update

Example 6. This example checks whether the id column is set up as a spin control. If so,it sets the spin range to 0 through 10:IF dw_1.Object.id.EditMask.Spin = "yes" THEN

dw_1.Object.id.EditMask.SpinRange = "0~~~~10"END IF

Datawindow Object Properties:A subset of the properties can be used with the SyntaxFromSQL function to generateDataWindow source code. You can use that code in the Create function to create newDataWindows.The following topics list the properties for each object within the DataWindow and for

keywords for SyntaxFromSQL.
